Chlorine and oxygen can bond in many ways:

• chlorine monoxide radical, ClO•, chlorine (II) oxide radical
• chloroperoxyl radical, ClOO•, chlorine (II) peroxide radical
• chlorine dioxide, ClO
  2, chlorine (IV) oxide
• chlorine trioxide radical, ClO
  3•, chlorine (VI) oxide radical
• chlorine tetroxide radical, ClO
  4•, chlorine (VII) oxide radical
• dichlorine monoxide, Cl
  2O, chlorine (I) oxide
• chlorine peroxide, Cl
  2O
  2, dimer of chlorine monoxide radical or ClO dimer, chlorine (I) peroxide
  • chloryl chloride, ClO
    2Cl, chlorine (0,IV) oxide
  • chlorine chlorite, ClOClO, chlorine (I,III) oxide
• dichlorine trioxide, Cl
  2O
  3 as O–Cl–ClO

  • dichlorine trioxide, Cl
    2O
    3 as possible isomer Cl–O–ClO
    2, chlorine (I,V) oxide
  • dichlorine trioxide, Cl
